The ViewSizer 3000™ uses innovative hardware and software to provide true distribution information for polydispersed nanoparticles in the range from 10 nm up to 2 um, something that is not possible with either Dynamic Light Scattering (DLS) nor nanoparticle tracking analysis . Other distinct advantages include the ability to obtain information about concentration and particle kinectic processes such as: particle aggregation, dissolution, swelling, growth and shrinkage. Compared with other systems in the marketplace, the ViewSizer 3000™ offers serveal distinct advantages including no need for calibrations standards and without requiring any prior knowledge of the material's refractive index.

How it works:

Particles are illuminated by 3 separate lasers and their scattering is imaged by a microscope objective while images captured by video. The resulting video shows the motion of each individual nanoparticle. By taking advantage of modern video cameras and computer speed, the motion of each particle is tracked to determine the diffusion coefficient, and, from that, the size of each particle.
